About the fps used for sampling

[zhuzhu18]

Why is the fps of the original video (before resampling and double padding) used to calculate the number of frames for sampling intervals, instead of the target_fps after resampling and double padding?I think there is a discrepancy here.

@zhuzhu18 Hi, thank you for reporting the bug. This code is borrowed from HERO_video_feature repo, which also seems to have the same bug. I'm glad that you send us a PR.
